Two large-scale Conshohocken office buildings are about to be sold in a pair of back-to-back real estate deals.

Five Tower Bridge, the 223,736-square-foot office building at 300 Barr Harbor Drive, will be purchased by Equus Capital Partners of Newtown Square; and Eight Tower Bridge, a 16-story, 345,000-square-foot facility at 161 Washington St., will be bought by American Real Estate Partners of Herndon, Va., writes Natalie Kostelni at bizjournals.com.

Two other large properties in the area are also on the market. Four Falls Corporate Center, which stands next to the Schuylkill Expressway in West Conshohocken, is being put up for sale for a second time. The Arden Group, the building’s owner, initially put it up for sale in 2015 but eventually de-listed it.

In addition, The Millennium office complex, which totals 196,769 square feet, came up for sale in August.

The last large office property to trade in Conshohocken was in January 2016 when 300 Four Falls, a 297,320-square-foot building, sold for $98.4 million, or nearly $340 a square foot.
